I'm looking to import a PNG or JPEG with a design I made on my computer and highlight where I want three images to go within this "background" or template. How do I do this?

Thanks!

This isn't possible yet in the way you describe. I plan on building this in the future.
In the meantime you can make a background image for the collage

Easiest way to do this currently is write down all your margin settings and then take a session. download the resulting strip to your computer and use a free app like www.canva.com to decorate the strip and then save it as the new background file.
actually canva has an ipad app and it works great on the ipad and its free.
